I've been trying to find a silent off-pulse generator that can respond to inputs as little as 4 ticks apart, meaning anything involving toggling torches to generate the pulse is out, since they toggle twice for each input (off then back on). Specifically, it will need to output an off-pulse of 2 ticks when it receives an on signal of as little as 2 ticks (although 1 would be fine), and be able to do so rapidly without torch burnout being a factor. The only silent off-pulse generators I've been able to find rely on the torch toggling thing, so I was hoping somebody knows one that doesn't.
Update: I've been trying to come up with something myself, but I'm not having much luck. The only way I can think of to interrupt a signal without toggling a torch is a comparator in subtraction mode, so this is what I've come up with so far:
The only way to get a 2-tick output, though, is to set the repeater to 3 ticks, which makes it so it can't cycle any faster than 6 ticks. So it's back to the drawing board.
Edit: I should clarify that it can in fact go down to a 4 tick cycle, but you only get a one tick pulse when you do so, so it doesn't suit my purposes.
I was coming at it the wrong way. Instead of inventing something that's an off-pulse generator from the ground up, it's a lot easier to just take an existing on-pulse generator and invert the output. That's a bog-standard comparator on-pulse generator with the output fed into a comparator inverter, and it meets all my requirements. Problem solved!
Edit: First version was unnecessarily complex, simplified it and posted a new picture.
